OILING ATTACHMENT FOR TROMBONES.

SPEGIFIGATION forming part of Letters Patent N o. 677,965, dated July 9,1901.

Application led February 11, 1901. f Serial No. 46,911. (No model.)

the trombone and will be constructed and arranged to supply oil whendesired to the faces of the tubes with which the slide is engaged.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view showing the trombone with the attachmentin place. Fig. 2 is an enlarged detail View showing a portion of thesides of the slides and of the tubes with which they are engaged,portions thereof, as also the slide-brace, being shown in section. Fig.3 is a section taken through the slide, the tubes, and the slide-bracein a plane at right angles' to that of Fig. 2. Fig. 4. is a detailperspective view of the spindle connected with the oil-hole covers foroperating them to uncover the holes. Fig. 5 is a detail perspective viewshowing one of the oil-hole covers.

Referring now to the drawings, there is shown a trombone including atube 10, with which is connected the bell 11 and a second and paralleltube 12, with which is connected the mouthpiece 13, Vthese tubes havingthe usual brace 14. Upon the tubes lO and 12 isy disposed the usualU-shaped slide l5, having a cross-brace 16, which serves the purpose ofa handle for reciprocating the slide in the formation of the differenttones. The brace 16, as usual, is formed of a section of tubing havingits ends fitted against the sides of the slide and provided withreinforcements, and in the sides of the slide and communicating with theinterior of this tubular brace 16 are perforations 17 and 18, throughwhich oil may be fed from the tubular brace to the interior of theinterior of the brace at a point midway of its ends and at the underside thereof, and this nipple has a closing-cap 20, adapted to bescrewed thereonto to prevent egress of the oil through the nipple. Toregulate the supply of oil from the brace to the slide, adjustableclosures 2l and 22 are provided and having stems 23 and 24E, which areslidably engaged with a supporting-frame within the brace 16. This framecomprises spaced side plates 25 and 26, having connecting cross-pieces27, and it-is with openings in these cross-pieces that the stems areengaged. The closures are held normally in position to close or coverthe openings by helical springs 2S, disposed upon the stems and betweenthe closures and the adjacent end pieces of the supporting-frame.

To move the closures from their operative positions to permit of passageof oil to the parts to be lubricated, a spindle 29 is rotatably mountedin the frame, within the brace 16, and has radiating fingers 30 and 3lat diametrically opposite points thereof, and these lin gers are engagedwith eyes 32 and 33 at the ends of the stems of the closures. Thus ifthe spindle be rotated in one direction the fingers will be moved toraise the closures from the oil-holes and the oil may pass into theslide,and if the spindle be released the springs will return theclosures to their operative positions. To rotate the spindle, a shaft 34is provided and is passed inwardly through the cap 20 and has its innerangular end engaged With a corresponding socket in the end of thespindle, the outer end of the shaft having a knob 35 for rotating it.The nipple being at the lower side ofthe brace 16, it does not interferewith the fingers that grasp the brace, the brace being grasped with thelirst and second fingers at the under side and with the thumb at theupper side, and by operating the spindle at any time a supply of oil maybe fed to the parts to be lubricated.

It will be understood that in practice various modifications of thespecific construction` shown may be made and that any suitable materialsand proportions may be used for the va rious parts without departingfrom the spirit of the invention.

What is claimed is- 1. In a trombone, the combination with the slide andthe tubes with which it is engaged, of a lubricating device disposedbetween the sides of the slide and connected with the interior of bothsides of the slide to supply alubricant thereto.

2. In a trombone, the combination with the slide, and the tubes Withwhich it is engaged, of a lubricating device carried by the slide andconstructed and arranged to supply a lubricant to the tubes with whichthe slide is engaged.

3. In a trombone, the combination with the slide and a hollow bracetherefor, said slide having openings therein communicating With theinterior of the brace, of adjustable closures for the openings, saidbrace having an opening for the introduction of a lubricant.

il. In a trombone, the combination with the slide of a tubular bracehaving communication with the slide and adapted to receive a lubricant,closures for governing the communication between the brace and slide, arotatable spindle, and connections between the closures and spindle foroperating the closures, said brace having a filling-opening.

5. In a trombone, the combination with the slide of a tubular braceconnecting the sides thereof, said slide havingopenings leading to theinterior of the brace, a frame Within the brace, closures for theopenings having stems slidably engaged With the frame, a spindle lin theframe having lingers with which the stems are engaged to operate them tolift the closures from the openings, helical springs disposed upon thestems between thc closures and frame to hold the closures yieldablyinoperative positions, and means for rotating the spindle.

In testimony that Iclaim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

FRANK ENNIS.
